Koin is an abundancy-based currency. That means that your Koin account will continue to slowly increase by itself. But it doesn't mean you can just live off the increase without working.
Every January, no matter who you are or what you earn, you will receive the equivalent of Ж1,000 per month (Ж12,000). After you recieve this amount, you will need to work/trade/create/provide a service in order to earn Koin.
If you start using Koin through the middle of the year, you will recieve the equivalent of Ж1,000 per month left before January. For example, if you begin to use Koin at the beginning of July, you will recieve Ж1,000 per month (Ж6,000).
